Title: Method for controlling the temperature of steel strip in the cooling zone of continuous annealing furnace
Inventor: DANOUCHI KUNIAKI
IPC: C21D11/00
Filed: 1984-12-14
Granted: 1989-07-31
Abstract: In the cooling zone of a continuous annealing furnace, steel strip passes over a series of cooled rolls, while cooling gas is blown against the exposed faces of the strip.  The rate of cooling is controlled first by varying the flow of cooling gas, then the angle of contact between strip and rolls, and finally the temperature of coolant passing through the rolls.  Alternatively, cooling gas flow and roll contact angle may be varied simultaneously.  Gas jet coolers are preferably opposite the cooling rolls, but may, alternatively or additionally, be upstream or downstream of them.

Title: Method for measuring gauss by nuclear quadrupole resonance
Inventor: CHO SUNG-HO
IPC: G01R33/44
Filed: 1991-09-24
Granted: 1996-01-18
Abstract: The method for measuring gauss using magnetic moment value under low region(greater than 0.1 ma) of constant magnetic field, uses a single crystal of (AH2)6N4, as a magnetic detection pin, of which asymmetric value of nuclear quadrapole resonance is zero. The method includes the steps of: a) reading two resonant frequencies with digital frequency meter after connecting the detection pin to nuclear quadrapole resonance apparatus; b) recording the read resonant signal to analog recorder; c) converting difference from two numbers of resonant oscillation to value of magnetic filed; and d) displaying the converted value on digital displayer.
